  • Input processing includes Gain, Mute, Link, High-cut, Low -cut, Noise gate, 5PEQ, Phase, Delay.
  • Output processing includes Crossover, 6PEQ, Gain, Mute, Compressor/Limiter, Phase, Delay, Link.
  • Every input and output can do matrix assign freely.
  • Adjustable PEQ frequency, Gain and Bandwidth, the gain step is 0.1dB, we can choose style: Peak, H-shelf, L-shelf, LP-6dB, LP-12dB, HP-6dB, HP-12dB.
  • The style of all High-cut, Low-cut filter and Distributor Unit: Butterworth, Linkwitz- Riley, Bessel, Slope is-6dB/oct ~-48dB/oct.
    Adjustable compressormiter threshold, soft knee, ratio, attached time and release time. Noise gate’s threshold, hold time, attached time and release time can be adjustment.
  • The parameters of input and output adjusting are linkable, revisable input and output channels.
  • All delay module’s delay time can reach over 680ms the step is: 0.021ms.
  • Parameter setting of each channel can copy freely, build-in signal generator.
  • Input and Output on the front panel are equipped with 5-segment high precision level indicators, key indicators, security protection function.
  • 30 user preset, 1factory preset, device parameter and single preset file can save in computer; it also can download from computer and save in
    the device. The device itself can store multiple preset parameters and recall freely. With PC software, one-key online made the operation more
    convenient.
  • USB and RS232 controlling ports, Online remote control and 255 units linkable through Rs485.
